The ABR is a dedicated breakthrough analyzer with fully programmable operation including control of total pressure, flow rate, composition and temperature. Samples are loaded into interchangeable reactor beds and dried in-situ with purge gas or vacuum at elevated temperature. Reactive gas mixtures are then flowed through the bed, and the downstream composition determined in real-time with an integrated mass spectrometer.

The ABR is primarily designed to meet the needs of researchers wishing to characterize the gas separation properties of small quantities of novel sorbents such as metal-organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs), covalent organic frameworks (COFs) and related porous materials without the time or expense of synthesizing larger sample quantities.
